Either of" iheso inclinw ifiions can readily be obtained by correspondingly moving the swivcl member with rcspect to the rod 23 so as to more the fork 13 laterally of the vehicls, or in other words by rocking she control rod 526 about ihis rod 23. To reflect this lateral movement of the swivel insmhor, I desirably do not. pivot. it dire-ct to the depending; rod 23 but mount. it on a threaded stein 524- which permits the swivel member to be adjusted lat orally of the machine. For example, Fig. 4: shows the rigid depending stem 23 as carry ing: a collar which supports a sleeve 26 while leaving the latter free to rotate on the stem, and this sleeve 26 has a horizontal stem 24 pinned i'.() it. Threaded upon this stem 24 is ii. bushing 27 which aii'ords a bean inp; for thc swivel member 22 through which the control rod 20 extends and to which the hiltcr is clamped by sct screws Upon loosening these sci; screws, tho control rod can he slid backward or forwnrd ihrough ills swivel member 22, thorohy changing the inclination of the auxiliary brush forwardly or rearwarclly fi ho machine.

Somewhat the depending stem 23 I provide a latching member rigidly se- (urcd to the frame of the machine andliaving Forks through either of which the corn irol rod 20 may rxtend, so that this rigid guide will cooperate with the swivel member i .so .tlmt it always slopes towsrzls the 4 laterally of :1 rehiclo so ihirt the. con

- toward the machine 19 on the forward end of the control rod. Consequently, by moving the swivel member laterally outward of the machine, I move the fork-19 in the same direction and hence can secure such a tilting of the shaft of the auxiliary brush as is shown inl ig. 9, while by moving the swivel member-'22 laterally (which is done by adjusting the bushing 27) I can tilt this brush shaft in the. opposite lateral" direction as shown in Fig. 8.

The latching member 29 desirably has at least two forks, of which one (marked 30 in F ig. 5) is relatively short, so that an engagementv of the control rod with this shorter fork will rock the control rod about the stem 24 supporting the swivel member and' hence will lift the brush clear of the gutter or other street portion. The other fork: extends considerably higher, so that the control rod when snapped into the latter will be at a more oblique angle to the street and hence will lower the brush to the surface of the street. This taller fork may be provided .with simple means for effectively varying its height, as by providing it with transverse bores interchangeably adapted to receive a spring cotter Ellagainst which the control rod can be swung by the action of the weight of the auxiliary brush in rocking the swivel member about the horizontal stem 24. The rear end of the control rod desirably is bent upward and terminates in a handle within convenient reach of the driver of the machine so that the driver can readily move the control rod to snap the latter into one or the other fork of the latching member, after having adjusted the cotter pin 31 according to the extent to which the auxil-. iary brush is to be lowered in practice, which in turn may depend on the extent to which this brush has become worn.v

To avoid a waste of power when the gutter-cleaning brush is not in use, I desirably do not connect the stem Q'directly to the shaft 7 of this auxiliary brush, but interpose a clutch arranged for automatically severing the driving connection when the auxiliary brush raised off the surface of the gutter or street. Thus, Fig. 2 shows the shaft 7 of the brush as splined to a sleeve 32 which is fastened to a collar 33 having downwardly directed lugs engaging corresponding notches in a clutch disk 34, fastened to the stem 9 which has heretofore been described as driven through thegears 12 and 13 during the operation of the vehicle. lVhcn the .brush is'lowered, the lugs on the collar 33 engage the continuously rotating clutch disk 34., so that the latter rotates the s eeve 32 with it and consequently also rotates the brush shaft 7 and the brush carried by the latter. However, a raising of the brush lifts the teeth on the collar 33 out of engagement with the clutch disk 34, thereby discontinuing the rotation of the auxiliary brush when the latter is in its raised position.

From the above it will readily be seen that after adjusting the swivel member to'afford the desired lateral tilting of the guttercleaning. brush and likewise adjusting the control rod to afford the desired rearward tilting, the operator can instantly throw the auxiliary brush into or out of service by simply dep'reming the handle on the control rod and snapping the latter from one fork of the latching member 29 to the other. Then, if a difierentslope of the gutter should require an altered tilting of the auxiliary brush, the needed adjustment can easily be made at the side of the machine, and the vertical stop means (here shown in the form of a cotter pin 31) can likewise be moved to allow for the gradual wear on the brush.

However, while I have heretofore described the appliance .of my invention in a highly desirable embodiment, I do not wish to be limited to the details of construction and arrangement thus disclosed, it being obvious that many modifications might be made without departing from the spirit of my invention or from the appendedelaims.

For example, the lateral adjiistnient' of the swivel member as provided by thehorizontal stem 24: might be omitted and the swivel member might be pivoted directly on the depei'iding stem 23 as shown in Fig. 10,in which case the desired change in the lateral tilting of the gutter cleaning brush can be both laterally and rcarwzlrdly of the machine, and separate adjustable means for maintaining predetermined lateral and rearward inclinations of the said shaft regardless of the movement of the machine.

In a street sweeping machine, a guttercleaning brush mounted on a downwardly directed shaft arranged for permitting adjustment thereof in directions both lateral and rearwardly of the machine, means for adjusting the re: rward inclination of the shaft, means for varying the lateral inclination of the shaft, and means under control of the driver for raising and lowering the brush without effectively altering the inclination of the shaft in either of the said directions.
